Stacked Half-Pie menus
Tobias Hesselmann, Stefan Flöring, Marwin Schmitt · 2009
Hierarchical menus can be found in many of today's software applications. However, these menus are often optimized for mouse or keyboard interaction and their suitability for touch screen-based interactive tabletops is questionable. On touch based interfaces, screen occlusion by the user, menu item size and the usage of intuitive navigation paradigms are essential aspects that need to be considered. In this paper we present our approach: "Stacked Half-Pie menus" that allow visualization of an unlimited number of hierarchical menu items as well as interactive navigation and selection of these items by touch. Our evaluation shows a fairly high usability of touchable half-pie menus, making them an interesting alternative to other established menu types on interactive tabletops.
